Subject: [PATCH] jet: fix native image with GraalVM 25.2.4

GraalVM 25.1 removed automatic feature discovery, so explicitly
register graal-build-time's InitAtBuildTimeFeature. Also set Jet's
native-image property so its native patches are applied.

Add an install check covering JSON-to-keywordized-EDN conversion.
